Product Certification
Product packaging 
1. Principles of Packaging Design
Protection Shock proof and buffering: precision accessories (such as instruments and valves) need to be filled with foam, bubble film, pearl cotton, etc. to avoid damage caused by transportation shock.
Moisture and rust prevention: Metal components (such as pipelines and flanges) need to be coated with rust prevention oil and packaged with moisture-proof film or vacuum. Desiccant should be added during sea transportation.
Anti pressure and anti drop: Heavy accessories (such as burners and drums) are reinforced with wooden boxes or steel frames, indicating the load-bearing direction and stacking layer limits.

2. Standardization and identification
Comply with international transportation standards (such as ISO, ISTA), indicate weight, size, lifting point, "fragile", "moisture-proof", "upward" and other markings.
Dangerous accessories (such as fuel injectors) must be labeled with UN certification and comply with the International Maritime Dangerous Goods Code (IMDG).

3. Container division strategy
Small items (bolts, washers) should be packaged in a uniform size box to avoid loose parts; Large items (heat exchangers) are individually customized in wooden boxes with supporting frames inside.

Product transportation
Transportation mode selection
1. Shipping by sea
Suitable for bulk accessories such as steel plates and large pipelines, pay attention to container size (20GP/40HQ) and load balance.Sea freight requires anti salt spray treatment, with moisture-proof agents placed inside the container and sealed.

2. Land transportation
Heavy accessories (over 3 tons) require flatbed trucks or low chassis vehicles, and routes should be planned in advance to avoid height/weight restrictions.Cross border transportation inspection of various countries' requirements for wooden packaging (such as ISPM15 fumigation certificate).

3. Air freight
Urgent small items (electronic controllers) should be prioritized for air transportation, and the weight of each item should be controlled (usually<100kg) to reduce packaging weight and save costs.

FAQ:
Frequently Asked Questions about Biomass Stoves (Q&A)

Q1: What should I do if the biomass grate gets stuck?
A1:
-Reason: Fuel is too long (such as uncrushed straw), foreign objects are mixed in (stones/metal), and the gap between the grate is too small.
-Emergency response:
1. Immediately stop the machine and reverse the grate 2-3 times to try automatic slag cleaning
2. Manually clear the obstruction (requires wearing protective equipment)
3. Adjust the discharge size of the crusher (recommended ≤ 5cm)
-Preventive measures:
-Install magnetic separator to remove metal impurities
-Regularly check the gap between grate plates (standard: straw 8-12mm, particle 3-5mm)

Q2: How to solve the problem of rapid burning of grate plates?
A2:  
-Fault diagnosis:
-Localized burn through → uneven air distribution (check the partition plate of the air chamber)
-Overall deformation → Material not up to standard (requires heat-resistant steel above ZG40Cr25Ni20)
-Surface oxidation peeling → combustion temperature exceeds the limit (≥ 1200 ºC, water cooling system needs to be installed)
-Improvement plan:
-Upgrade to tungsten carbide spray furnace grate (life extended by 3 times)
-Optimize the secondary air ratio (control the furnace temperature between 900-1100 ºC)

Q3: How to adjust the deviation of the grate?
A3:  
-Testing method:
-Measure track deviation with a laser level (allowable error ≤ 2mm/m)
-Check the tension of the chain (the sag should be less than 3% of the sprocket center distance)
-Correction steps:
1. Adjust the eccentric shaft of the driven wheel
2. Tighten the tension rod bolts on both sides (synchronous operation required)
3. No load operation test (speed ≤ 50% of rated value)

Q4: How to optimize ash with high carbon content (>15%)?
A4:  
-Combustion adjustment:
-Reduce grate speed (recommended 2-5m/h for straw fuel)
-Increase the air volume in the burnout zone (accounting for 20-30% of the total air volume)
-Equipment renovation:
-Install a burnout air nozzle (angle 15 ° downwards)
-Adopting a multi-stage grate (such as 3-stage reciprocating+1-stage fixed)

Q5: What should I do if there is abnormal pressure in the hydraulic drive system?
A5:  
-Fault Tree Analysis:
A [Low pressure] -->B (Oil pump wear)
A -->C (solenoid valve stuck)
D [pressure fluctuation] -->E (oil contamination)
